The FANUC I/O Link can be extended to the maximum length of 200 m
(when a relay is not used) with optical fiber cables using an optical I/O
link adapter.
NOTE
In the following cases, use an optical fiber cable.
When the cable is more than 15 meters long.
When the cable runs between different cabinets and it is impossible to
connect the cabinets with a grounding wire of 5.5 mm
2
or thicker.
When there is concern that the cable is influenced by strong noise; for
example :
When there is a strong electromagnetic noise source beside the cable
such as a welding machine.
When a noise generating cable such as a power cable runs for a long
distance in parallel with the cable.
